Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640854, here are decompositions:

31 + 8640823 = 8640854
37 + 8640817 = 8640854
67 + 8640787 = 8640854
73 + 8640781 = 8640854
151 + 8640703 = 8640854
163 + 8640691 = 8640854
307 + 8640547 = 8640854
373 + 8640481 = 8640854

Showing the first eight; more decompositions exist.
